CHARLES MORRILL, OF NEW YORK, N. Y.

IMPROVEMENT IN FASTENINGS FOR MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 116,076, dated June 20,1871.

To all whom it may concern:

Be it known that I, CHARLES MoRRILL, of the city of New York, in thecounty and State of New York, have invented certain new and usefulImprovements in Window-Sash Fasteners; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing forming part of thisspecification, in which- Figure l is a plan or top view of my inventionas applied to the top and bottom rails of. the lower and upper sashes,respectively, in a locking position. Fig. 2 is a side elevation of thesame. Fig. 3 is a side elevation, showing the device unlocked to allowthe sashes to be raised or lowered.

My invention consists in the combination, to produce a window-sashfastener, of a slidingtoothed jaw and a stationary-toothed jaw secured,respectively, to suitable holding-plates, and an operating or lockinglever, whereby a reliable, simple, and efficient device for looking orfastening window-sashes is provided.

A B designate the two jaws of the fastener. The jaw A is permanentlysecured to or cast upon a plate, 0, which latter is designed to besecured on the top rail of the lower sash in the ordinary position. 0 isa similar plate, designed to be secured on the top of the lower rail ofthe upper sash in the ordinary position.

This plate 0 carries two lugs, to a, between which there is pivoted thebifurcated or forked lower end of a locking-lever, D. The jawB isprovided with a rectangular slot or a horizontal and vertical slot, 12b, and through the horizontal slot 1) the pivot cor fulcrum of the leverD passes; and through the vertical slot 11 a second pivot, 0, passesfrom one fork of the lever to the other. It will be observed that thepivot a passing through the slot b, in addition to its being a fulcrumfor the lever, serves to keep the jaw down upon the plate, while thepivot c, working in the vertical slot 12, moves the sliding jaw B backand forth accordingly as the lever is moved upward or downward.

As an equivalent for the slot 1) and pin passing through it, I willremark that the jaw B may be provided with flanges at its bottomprojecting outward from each side, and the lower end of the lever berounded and caused to presson such flanges, in which case the two forksof the lever would be independently pivoted. Each jaw A B is providedwith one or more teeth and corresponding recesses or dental spaces, sothat when the two jaws are drawn together the teeth will interlock orengage with each other and form apermanent fastening. To facilitate theengagement of the two jaws the top of the stationary jaw B is rounded,so that when the said jaw B is brought within the embrace of the forkedend of the lever a downward pressure on the latter will draw the movablejaw up so as to properly engage with the stationary jaw, and the twojaws will thus be held together in a very secure and reliable manner, aswill be obvious by reference to Figs. 2 and 3.

My invention provides a secure, simple, reliable, and ornamentalwindow-sash fastener.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the sliding slotted-toothed jaw B, thestationary-toothed jaw A, holding plates 0 G, and locking-lever D, allconstructed, arranged, and operating substantially as and for thepurposes herein specified.
